Here is the machine

The McAfee SiteAdvisor Service service failed to start due to the following error:
The system cannot find the file specified.

I uninstalled mcaffee when i first got it. I just searched my C drive and got rid of all remaining mcaffee programs. Hope this fixes it. Thanks guys! i got a week till i go back to school and if i went back without a computer because it was off being fixed for two weeks, i would needless to say be screwed.
